Among the electromagnetic guns and aquatic drones demonstrated earlier this month by the US Navy’s research office was a robotic seaglider – one of many that the Navy has commissioned to study Arctic ice, according to online reports published Sunday by NPR.

Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s.

A dense mass of Pacific walruses, estimated to be 35,000 strong, has gathered on a beach in northwest Alaska, approximately five miles north of Point Lay. Scientists believe this unprecedented number of animals has been driven to shore by a lack of sea ice.

The Arctic Ocean which is located in the Northern Hemisphere and mostly in the Arctic north polar region, is the shallowest and smallest of the world’s five major oceanic divisions. The International Hydrographic Organization recognizes it as an ocean, although, some oceanographers consider it as the Arctic Mediterranean Sea or simply, the Arctic Sea, classifying it a Mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be considered as the northernmost...

Baffin Bay, which is located between Baffin Island and the southwest coast of Greenland, is a marginal sea of the North Atlantic Ocean. It’s connected to the Atlantic by Davis Strait and the Labrador Sea. A narrower Nares Strait connects the Baffin Bay with the Arctic Ocean.
The Baffin Bay is an arm of the Atlantic Ocean that is bordered by Baffin Island towards the west, Greenland towards the east, and Ellesmere Island towards the north. It is connected to the Atlantic through the Davis...

The Bearded Seal (Erignathus barbatus), or Square Flipper Seal, is a seal found in or near to the Arctic Ocean. Its most characteristic feature is the whiskers on its face. When dry, the whiskers curl up giving the bearded seal a raffish look. Other distinguishable features are the square fore-flippers and thick bristles pn their muzzles.
Adults are grayish-brown in color, darker on the back, rarely with a few faint spots on the back or dark spots on the flanks. Occasionally the face and...

Arctic Circle -- The Arctic (Land of the Midnight Sun) is the area around the earth's North Pole while antarctic is in South Pole. It includes parts of Russia, Alaska, Canada, Greenland, Lapland and Svalbard as well as the Arctic Ocean.
The Arctic Circle is one of the five major circles of latitude that mark maps of the Earth.
Everything north of this circle is known as the Arctic, and the zone just to the south of this circle is the Northern Temperate Zone.
This is the parallel of...
